Hello,
our roofing company told us that they want to install a Delta-Sd Flexx renovation vapor retarder under the insulation on top of the rafters instead of a vapor barrier. They say this is better.
This concerns a new building where we want to leave the roof structure visible from the inside. The construction is planned as follows:
1.) Rafters 2.) 19mm visible boarding (spruce wood) 3.) Delta-Sd Flexx renovation vapor retarder (?????) 4.) Bauder PUR insulation on top of the rafters 180mm WLG026 coated with mineral fleece 5,6,7) Battens / roofing
He said that if I insisted, he would also install a PE foil instead of the Delta vapor retarder.
Does anyone have experience with what is the most sensible now? - I can’t really do more than rely on him as an expert. But one is still allowed to have doubts :-)
Many thanks!
